Empty Mtn Mesh Flat is an empty backfield concept out of Y Off Trio Close WK built around a classic mesh combo to one side with a flat route underneath to give the quarterback a quick outlet. The mesh crossers rub across the middle of the field to create natural traffic against man coverage while the flat route stretches the underneath zone horizontally, making this both a man beater and a zone beater depending on the shell. With five receivers out and no back to check release, the primary read progression starts with the shallow mesh crosser working away from initial pressure, then works to the second mesh route sitting behind it, and finally clicks to the flat as the checkdown against a hard blitz.
Read the linebacker depth at the snap, since shallow LB drops directly into the mesh crossing lanes and can jump the shallow route if he sits instead of covering flat responsibility. Identify man versus zone by watching if defenders trail the mesh crossers through the pick or if they sit and wait in zone drops, since the crossers separate easily against man but get picked off passing lanes in zone. Watch for a user controlled defender spying the mesh area or lurking underneath, since a smart user can rob the shallow crosser and force you to hold the ball longer than the empty protection allows. Cover 3 and Cover 4 zone shells with disciplined underneath defenders shut this play down quickly, since the mesh has nowhere to work against sinking zone coverage. Blitz packages with man coverage behind them are actually favorable for this concept, since the flat route and mesh crossers both beat man leverage and give a fast answer against pressure.
Check the pre-snap alignment for man coverage indicators like tight press corners or a single high safety, since the mesh crossers thrive against man because defenders have to fight through traffic to stay attached.
Use the flat route as your blitz beater on third and short or third and medium, since it gets the ball out fast against nano blitzes and five or six man pressure looks.
Hot route the backside receiver into a deep option or drag if you see a Cover 3 shell, since the base concept is designed to attack man and can get grounded against a sound zone drop underneath.
Pair this play with Mtn Mesh Flood in the same set to keep the defense guessing between a true mesh crossing concept and a flood concept, since both start with similar formation and receiver alignment but attack different levels.
Use in obvious passing situations like second and long or third and medium when you expect man coverage rotation, and avoid calling it into heavy zone shells without adjusting the outside routes first.
